This can be a dangerous change and probably does not have the intended
effect ((project) global ccache dir) due to
| do_clean[cleandirs] += "${CCACHE_DIR}"
imo, this class should be removed completely (${PN} local ccache dirs do
not make any sense) and the only useful part
| CCACHE_DISABLE[unexport] = "1"
should be solved by http://patchwork.openembedded.org/patch/32787/
